public class SimpleContentViewerUI

implements javax.help.event.HelpModelListener, javax.help.event.TextHelpModelListener, javax.swing.event.HyperlinkListener, java.beans.PropertyChangeListener, java.io.Serializable

Title: SimpleContentViewerUI.java

Description: Based on SimpleContentViewerUI in javax.help.plaf.basic, which comes with JavaHelp, which comes with Java1.4, and is written by Sun Microsystems. More information on JavaHelp can be found at http://java.sun.com/products/javahelp/faq.html But this version doesn't call setBackingStoreEnable(true), which is a deprecated method (as of java1.4) anyway.

This simple modification has the net effect of allowing images displayed in help content windows to not be mangled (actually, they mysteriously disappear) when the scrollbar is first used.
